“…To the best of our knowledge, there is no systematic method to construct optimum sequences except for time-consuming and costly exhaustive computer search. However, one can construct sequences with high filter efficiencies by mapping from -ary -sequences, or construct longer sequences from known sequences with high efficiencies by product theorem [6]- [8].…”

“…In what follows, we refer to a sequence as being optimal for a given length if its efficiency , i.e., the ratio of the mismatched filter SNR to the matched filter SNR, takes on its maximum. In 1980, Ipatov published a table of optimum sequences up to length by computer search [8]. Further search results up to shown in [8] were originally found by Antweiler and Lüke.…”

“…In 1980, Ipatov published a table of optimum sequences up to length by computer search [8]. Further search results up to shown in [8] were originally found by Antweiler and Lüke. In fact, Ipatov presented a construction method for binary sequences with very high filter efficiencies by mapping from -ary -sequences.…”

In mobile communications, navigation, and radar applications, good periodic binary sequences are normally used with matched-filter technique. However, from the viewpoint of signal processing, there is no need to only consider the filter coefficients as binary. This letter presents a theoretical bound for real-valued mismatched sequence sets with zero correlation zone (ZCZ) and then proposes a method for constructing sets of optimal mismatched ZCZ sequences with respect to the theoretical bound for application in mismatched filtering.

This paper introduces a class of perfect binary sequence pair (PBSP), which is characterized by the impulseequivalent periodic autocorrelation function (PACF) and the length of N=2 k . The proposed PBSP can be generated from a class of difference set pairs (DSP). Considering the desirable properties of the proposed sequence pair, orthogonal frequency division multiplexing (OFDM) transmission with time-domain superimposed training is proposed. Simulation results show that our binary sequence pair is ideal for channel estimation in terms of complexity, accuracy and efficiency.

“…In mismatched filtering systems, if u and v have small non-trivial correlation values, then u can be used as sending sequence in the transmitter and we can use correlation computation to detect u when setting v as address code in the receiver [1,2]. Sequence pairs are said to have perfect correlation if the non-trivial correlation values are all zero.…”
